Microwave Spectrum, Structure, and Dipole Moment of Carbonyl Fluoride

Abstract

The microwave spectrum of carbonyl fluoride, COF2 has been investigated in the region 8–30 kMc. The following effective rotational constants have been obtained (Mc): C12O16F219C13O16F219C12O18F219a11813.4511814.6611813.48b11752.9911747.2710878.54c5880.915879.815653.32The structure calculated from these constants is rCF = 1.312 Å, rCO = 1.174 Å, ≰FCF = 108.0°. From measurements of the Stark effect the dipole moment is found to be 0.951±0.010 D.
